How to properly exit CAcroApp?

Question

I referenced Acrobat.dll in a simple C# Console program, and then wrote a couple of lines of codes to run Acrobat.

CAcroApp mApp = new AcroAppClass();
Console.WriteLine("Acrobat is running");
bool bClose = mApp.CloseAllDocs();
bool bExit = mApp.Exit();

However, while CloseAllDocs() return true, Exit() always return false.

And accordingly I can still see Acrobat process running in the Task Manager.

However, once the program ends, the process also gets killed automatically.

How can I make it so that I can close Acrobat process from within the program without having to exit the program as well?

From my experiance, the Acrobat process will close only when all related objects are garbage collected. To force collection, use the following code:

GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();

Note: Garbage collection only works when the related objects (e.g. mApp) are no longer in scope.
